The 2017 Zero S has 3 recalls, the most serious being an ABS control unit that can cause the brakes to behave unpredictably during a hard stop, raising the risk of a crash.
The ABS control unit may contain incorrect software or vehicle model information, which can cause the system to misfire or fail to modulate braking properly when it activates. There is also a turn signal concern affecting certain trim configurations: if a turn signal bulb stops working, the flasher unit may not speed up its flash rate to warn the rider, leaving the rider unaware that the signal has failed and other road users without a clear indication of the intended turn.
